PAKAGE-WRABPING MACHINE.

Specification of Letters Patent.

Application led September 27', 1918. Serial No. 255,958.

To all whom t may concern Be it known that l, SIMON COOPER, a citi- Zen of the United States, and resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Package -Wrapping Machines, of which the following is a specification.

llhis invention relates to package wrapping machines, having reference more especially to a machine for wrapping definite quantities of small boxes and their contents, such, for example, as boxes of matches.

The main object of my invention is to provide a machine whereby successive groups of boxes, or other articles, are automatically removed from a row or rows thereof, and wrappers applied to and effectively folded about the succeeding groups in such a manner as to produce, rapidly and economically, packages of uniform shape and size. i'

In the preferred form of embodiment of my invention herein disclosed juxtaposed rows of boxes (or articles ofsimilar form) are progressively advanced to a delivery station and predetermined numbers thereof are successively removed and associated with lengths of wrapping paper to the margin of which paste or the like has been properly applied, and each group of boxes with its associated wrapper is subjected to the sequential operations of etlicient folding and ironing instrumentalities.

My invention, generally stated, comprises a source of box supply whereby rows of boxes are advanced in an orderly manner to a delivery station; means whereby lengths oi' wrapping paper are fed adjacent such station; means whereby predetermined groups of boxes are successively removed from thc rows and imposed on the succeedinglengths of paper; means whereby each group of boxes-51nd its associated wrapper are delivered to a chambered structure and the wrapper thereby partially folded in such a manner as to embrace the bottom and sides of the group of boxes; means whereby said structure /is intermittently actuated to-pos tion the succeedingr chambers thereof for the reception of succeeding groups of boxes and their associated wrappers, and ,at the same time advance the contained boxes fand wrappers to succeeding stations; means whereby the 11p-projecting sides"l of each w'apper are folded upon thetop of the group of boxes; means whereby the end-projecting top, side and bottomy portions of the wrapper are successively `folded against the adjacent ends of the boxes and ,upon each other; and means whereby the end folds of the wrapper are ironed and smoothed so as to insure their close and intimate relation to each other and to the incased group of boxes, and thus complete the package preparatory to its discharge 'from the structure.

The invention also comprises novel features ofconstruction and operation, together with Ivarious combinations of parts, all of which will be hereinafter described and claimed. i

ln the drawings- Figure l is a plan of a wrapping machine embodying my "invention Fig. 2 is an elevation of one side of the machine.

Fig. 3 is an elevation of the opposite side thereof.

Fig. 4- is anjelevation' of the front end of the machine.

Fig. 5 is an elevation of the opposite end of the machine.

Fig. 6 is a horizontal section of the machine, as on the line G-ti of 2.

of the saine, as on the line T--T of Fig. i.

Fig. Fi is a transverse vertical section of thtl machine, as on the line 8--8 of Fig. 7.

Fig, is a similar section, but showing the nieehanisnis in the relative positions which they are caused to assume during a succeeding operation of the machine.

Fig. 10 is a j'icrspective of a trough struciure along which juxtaposed rows of boxes are fed and arranged for delivery in groups.

Fig. ll is an eniarged plan of the delivery end of the trough showing a group of boxes preparatory to discharge.

Fig. l2 is a transverse vertical section, enlarged, through the trough, showing a feedbelt and boxes positioned thereon. l

Fig. 13 is an elevation of the paper cutting mechanism. showing the movable cutter thereof in its raised or normal position.

Fig. lis a similar view shovving the movable cutter in its doivn position after severing the paper.

lug. l5 is a perspectlve of the cutter bar and theassociated cutter blades.

F ig. 16 is a perspective of the supporting frame for the cutter and feed-roll mechanisms.

Fig. l? is a section through said frame and feed-roll mechanism, as on the line 1'7-17 of Fig. l. i

Fig.l 18 is a vertical section through the feed-roll and cutter mechanisms, as on the line 18-l8 of Fig. l.

Fig. 19 is a perspective of a bearing box and cap member for one of the feed-roll shafts.

Fig. 2() is a similar' view of the arm and pin .of an eccentric connection for adjusting one of the upper feed-roll bearings.

Fig. 2l is a perspective of the intermittently-rotatable package receptacles and the associated Wrapper and boa support, together with their respective actuating elements.

F ig. 22 is a sectional elevation of one of the package receptacles and a portion of the the receptacle containing partially Wrapped boxes, and the support being in its loWermost position preparatory to the advancement of such 'receptacle to the next succeeding folding station.

Fig. 23 is a plan of the wrapper and box support, showing a W 'ap per and boxes thereon, and also indicating the positions of the surface pads of said support in relation to the end edges of the adjoining upstanding boxes.

Figs. 24, 25 and 26 are diagrams illustrating successive operationsof the 'wrapper and box support, the pressure plunger and the top .folding members in relation to each other and to `the intermittifntby rotatable package reteptaeles. ln Figi'. zo the fil-st eral folding' member for the. projeeting ends of the wrapper is indicated in 'folding position.

Fig. 27 is a diagram illustrating the operation of the end folding mechanism; the first end folder thereof being shown as retracted and the final end folder as in 4advanced or folding position.

28 is another diagram showing the final-end folder as retracted, also mechanism for ironing the end folds, together with mechanism for ejecting the packages successively from the receptacles.

Fig. :29 is a perspective of the pair of first end folding members.

Fig. 30 is a similar folding member.

Fig. 3l is a perspective of the ironing and ejecting mechanisms.

Fig. 32 is a similar view of. one of the top folding' members and its carriage.

Fig'. 3% is a similar view of the opposed pairs of top and bottom end folding members, and adjuncts.

' Fig. 34 is a sectional elevation of the acting end of one of the said end folding` members.

Fig. 35 illustrates, in perspective. the series of power shaft cams and the relation of their cam surfaces to each other.

Fig. 36 is a perspective of the paste-applying disk showing its relation to the web of wrapping material, and indicating' the interrupted marginal line of paste as applied thereby to the web, the feed rolls for the web being indicated by dotted lines.

Fig. 3T is a perspective of said disk and associated parts.

Fig'. 38 is a perspective of the paste hopper, the lower portion thereof being in section.

Figs. 39 to 44, inclusive, are perspective Vviews of the associated wrapper and boxes, showing the ivra p per in its successive stages of folding.

Referring to the drawings, designa-tes a supporting frame of suitable shape and size for its intended purpose; and 4G designates a main or drive shaft extending lon- `'itudinally of the frame and having its bearings in suitably-disposed boxes on the latter` which shaft is driven from a suitable source of poiver. ln the present instance the shaft is provided with a spur wheel 4T in mesh with a. pinion si@ on a shaft -tfl which has its bearings in suitably-disposed boxes on the main frame. The shaft -19 bears a spur wheel 5() in mesh with a pinion 5l on the shaft of an electric motor 52, and hence the power is transmitted through the described gearing to the main shaft. The shaft if) is provided with a suitable clutch any usual or approved construction, wherebyv the spur wheel 5() may be made fast or loose, as desired. The eomplen'ientary members of the clutch are indicated at 525. 5l.. respectively, in Figs. l and 6, the movable member 53 being pivotally connected to the loiver endlof a vertical shifting lever 55 'which is jointed at its upper end to a movable hand operated bar 56, as usual.

An intel'mittently-rotatable shaft 57 tends longitudinally of the frame and has its bearings in suitably-arranged boxes 58. This shaft bears a turret structure 59 havine' a series of peripheral chambers or review of the final end
